PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 364,961, dated June14:, 1887.

Application filed February 14, 1887. Serial No. 227,591. (No model.)

To aZ? whom it may concern:

Be it known that 1, JOHN SAMPLE, a citizen of the United States,residing at Nor-wood, in

the county of Norfolk and State of Massachusetts, have invented a newand useful PipelVrench, of which the following is a specificat1on,reference being bad to the accompanying drawings.

My invention consists in the devices and the combinations thereof,substantially as herenafter described, and specifically pointed out nthe claims, whereby a pipe wrench is termed comprising, essentially, ashank of two parts, providing a jaw at the end, and also at the front oran edge face, and an S-shaped piece, provided with a jaw at each end,pivoted to said'shank between said parts, so that it may be revolved tobring either jaw thereof opposite either jaw of the shank, there beingalsoa spring to press said S-shaped piece and the aws into workingposition.

In the drawings, Figure 1 is a side view of a wrench embodying myinvention. Fig. 2 is-a front view of the same. Fig. 3 shows a side View,and Fig. 4 a rear view, of the piece by ltself forming the shank andhandle.

The shank consists of two like parallel parts, a and b, there being aspace between them. These parts are joined at their inner ends to formone piece, which extended constltutes the handle A of the wrench. Theshank is serrated at the end to form ajaw, c, which is preferablysomewhat curved. The

shank is also serrated at the front or an edge face to form another jaw,d.

The Sshaped piece B is serrated at the lnner face of each end to formjaws c and f. This S-shaped piece is located between the parts a and bof the shank and pivoted thereto by a pin, in such a manner that thepiece B may be revolved between said parts to bring either jaw thereofopposite either jaw on the shank. By preference, one end of the S-shapedpiece is smaller than the other, a part of the serrated face of each jawthereof straight, and the pivot so placed that the smaller, 6, of thesejaws is somewhat nearer the pivot than th'e'larger jaw, f.

.A flat spring, 0, is fastened at one end on the rear face of the shankor handle in such a manner that the f rce end h may press against therear face of the piece B when either jaw thereof is opposite the end jawof the shank. That portion or projection at the end of the spring whichbears against the piece B is so that the wrench may receive a pipebetween either pair of jaws, as required. The jaws will be pressed tothe pipe by the spring, so as to be quickly and certainly brought toworking position. Pipes between the jaws of each pair are indicated bythe dotted liuesj and 7.1.

Not only is a large range of work provided for by bringing either thesmaller or larger jaw of the piece B opposite either jaw on theshank-which is effected by simply revolving the piece B but greatconvenience results from having a jaw at the end and also at the frontor. edge face of the shank, since a pair of jaws may thus be in the bestposition for the work.

I claim as my invention 1. In a pipe-wrench, the combination of a shankand an S-shaped piece, providing the opposite jaws, said shank being oftwo parts, and said S-shaped piece being located between said parts andpivoted thereto, so that it may make a complete revolution,substantially as'and for the purposes set forth.

2. The combination of the shank formed of two parts and providing twojaws, one at the end and the other at the front or edge face, and anS-shapcd piece pivoted between said parts, so that it may make a fullrevolution, and provided with a jaw at each end, sub stantially as andfor the purposes set forth.

3. The combination of the shank formed of two parts, a and b, providingtwo jaws, one, which bears against said S-shaped piece, and
